java - framework - spring mvc hibernate crud example eclipse

La inyección de dependencias con conexión automática falló; la excepción anidada es org.springframework.beans.factory.BeanCreationException:

Question

Estoy creando una aplicación web usando Spring, Hibernate, Struts y Maven.

Recibo el siguiente error cuando mvn clean install comando de mvn clean install :

org.springframework.beans.factory.BeanCreationException: Error creating bean with name ''com.project.action.PasswordHintActionTest'': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private com.project.action.PasswordHintAction com.project.action.PasswordHintActionTest.action; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No matching bean of type [com.project.action.PasswordHintAction] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}

La siguiente es la clase que tiene la dependencia Autowired:

import com.opensymphony.xwork2.Action;
import org.project.model.User;
import org.proejct.service.UserManager;
import org.junit.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.subethamail.wiser.Wiser;
import static org.junit.Assert.*;
public class PasswordHintActionTest extends BaseActionTestCase {
@Autowired
private PasswordHintAction action;
@Autowired
private UserManager userManager;
@Test
public void testExecute() throws Exception {
// start SMTP Server
Wiser wiser = new Wiser();
wiser.setPort(getSmtpPort());
wiser.start();
action.setUsername("user");
assertEquals("success", action.execute());
assertFalse(action.hasActionErrors());
// verify an account information e-mail was sent
wiser.stop();
assertTrue(wiser.getMessages().size() == 1);
// verify that success messages are in the request
assertNotNull(action.getSession().getAttribute("messages"));
}
}

Mi applicationcontext.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

<property name="settings">

<entry key="compass.engine.connection" value="target/test-index" />
</map>
</property>
</bean>

He agregado a mi configuración de contexto para escanear las dependencias de Autowired. Pero no estoy seguro de por qué sigue dando esta excepción.

Intenté agregarlo de la siguiente manera también, pero sigo teniendo la misma excepción.

<context:component-scan base-package="com.project.*"/>

ACTUALIZAR:

siguiente es la acción de sugerencia de contraseña

import org.project.model.User;
import com.project.webapp.util.RequestUtil;
import org.springframework.mail.MailException;
import org.springframework.security.core.userdetails.UsernameNotFoundException;
import java.util.ArrayList;
import java.util.List;
public class PasswordHintAction extends BaseAction {
private static final long serialVersionUID = -4037514607101222025L;
private String username;
/**
* @param username The username to set.
*/
public void setUsername(String username) {
this.username = username;
}
/**
* Execute sending the password hint via e-mail.
*
* @return success if username works, input if not
*/
public String execute() {
List<Object> args = new ArrayList<Object>();
// ensure that the username has been sent
if (username == null) {
log.warn("Username not specified, notifying user that it''s a required field.");
args.add(getText("user.username"));
addActionError(getText("errors.requiredField", args));
return INPUT;
}
if (log.isDebugEnabled()) {
log.debug("Processing Password Hint...");
}
// look up the user''s information
try {
User user = userManager.getUserByUsername(username);
String hint = user.getPasswordHint();
if (hint == null || hint.trim().equals("")) {
log.warn("User ''" + username + "'' found, but no password hint exists.");
addActionError(getText("login.passwordHint.missing"));
return INPUT;
}
StringBuffer msg = new StringBuffer();
msg.append("Your password hint is: ").append(hint);
msg.append("/n/nLogin at: ").append(RequestUtil.getAppURL(getRequest()));
mailMessage.setTo(user.getEmail());
String subject = ''['' + getText("webapp.name") + "] " + getText("user.passwordHint");
mailMessage.setSubject(subject);
mailMessage.setText(msg.toString());
mailEngine.send(mailMessage);
args.add(username);
args.add(user.getEmail());
saveMessage(getText("login.passwordHint.sent", args));
} catch (UsernameNotFoundException e) {
log.warn(e.getMessage());
args.add(username);
addActionError(getText("login.passwordHint.error", args));
getSession().setAttribute("errors", getActionErrors());
return INPUT;
} catch (MailException me) {
addActionError(me.getCause().getLocalizedMessage());
getSession().setAttribute("errors", getActionErrors());
return INPUT;
}
return SUCCESS;
}
}

Actualización 2:

applicationContext-struts.xml:

<bean id="passwordHintAction" class="com.project.action.PasswordHintAction" scope="prototype">
<property name="userManager" ref="userManager"/>
<property name="mailEngine" ref="mailEngine"/>
<property name="mailMessage" ref="mailMessage"/>
</bean>

Answer 1

Es necesario proporcionar un candidato para autowire. Eso significa que debe saberse que una instancia de PasswordHint brota de manera que pueda adivinar que debe hacer referencia a ella.

Proporcione al jefe de clase de PasswordHint y / o la definición de esa clase para obtener más ayuda.

Intenta cambiar el nombre de

PasswordHintAction action;

a

PasswordHintAction passwordHintAction;

para que coincida con la definición de frijol.

Answer 2

Utilice la exploración de componentes como se indica a continuación, si com.project.action.PasswordHintAction está anotado con anotaciones de estereotipos

<context:component-scan base-package="com.project.action"/>

EDITAR

Veo tu problema, en PasswordHintActionTest estás autowiring PasswordHintAction . Pero no creó la configuración de bean para PasswordHintAction para autowire. Agregue una de las anotaciones de estereotipos ( @Component, @Service, @Controller ) a PasswordHintAction como

@Component
public class PasswordHintAction extends BaseAction {
private static final long serialVersionUID = -4037514607101222025L;
private String username;

o crear una configuración xml en applicationcontext.xml como

<bean id="passwordHintAction" class="com.project.action.PasswordHintAction" />
